Sunflower Mammoth Grey Stripe HEIRLOOM Seeds

Helianthus annuus

Item #1039

Annual. This giant among sunflowers is
a fast grower that can reach
12' tall and produce 10" - 12"
flowers! Not fussy about soil,
it's very easy to grow and
drought tolerant. Grow in a
tight row to cover up that
not-so-pretty chain link fence
or make an attractive screen.
Edible gray striped seeds invite
birds in the fall (if you don't
eat them first!)
